Hi,

Here is my story how I got my system to work :)

My config:
• CPU – i7 2700k CPU
• Motherboard – Asus P8Z68-V/Gen3
• GPU – Radeon 6850 XFX (model HD-685X-ZNFC)
• 32 GB RAM
• OSX 10.7.5

BIOS
I use patched bios from:
http://biosrepo.word...s.com/asus/z68/

These are my bios settings, the rest is default or auto.

- http://dl.dropbox.co...1/osx/bios2.jpg
- http://dl.dropbox.co...1/osx/bios3.jpg

For my i7 2700k CPU I have set all x-Core Ratio Limit to 39. Set it higher if you want to overclock :)

BOOTLOADER
I use latest chameleon – anything above r1820 should be fine.

EXTRA
In extra folder I have:
• patched DSDT.aml file with proper audio section,
• SSDT.aml file with speedsteps - http://dl.dropbox.co...1.speed3900.zip
• SSDT-1.aml file with sata section (extracted from bios),
• in org.chameleon.Boot.plist I have set DropSSDT to Yes, GraphicsEnabler to YES, AtiConfig to Gibba, and UseKernelCache to YES,
• and smbios.plist with macmini 5.3 definition.

Speedstep works. Tested with MSRDumper and IOReg:

7,63 pts in Cinebench 11 and geekbench 14500 pts.

FakeSMC
I use this version of fakeSMC with plugins:

and hardware monitor to check temps, clocks, voltages and fans.

AUDIO
ALC892 kext from toleda with proper DSDT patch:
Name (_ADR, 0x001B0000)
			 Method (_PRW, 0, NotSerialized)
			 {
				 Return (Package (0x02)
				 {
					 0x0D,
					 0x05
				 })
			 }
			 Method (_DSM, 4, NotSerialized)
			 {
				 Store (Package (0x0C)
					 {
						 "subsystem-id",
						 Buffer (0x04)
						 {
							 0x36, 0x84, 0x00, 0x00
						 },
						 "subsystem-vendor-id",
						 Buffer (0x04)
						 {
							 0x43, 0x10, 0x10, 0x10
						 },
						 "layout-id",
						 Buffer (0x04)
						 {
							 0x7C, 0x03, 0x00, 0x00
						 },
						 "codec-id",
						 Buffer (0x04)
						 {
							 0x92, 0x08, 0xEC, 0x10
						 },
						 "device-type",
						 Buffer (0x11)
						 {
							 "ALC892"
						 },
						 "PinConfigurations",
						 Buffer (Zero) {}
					 }, Local0)
				 DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
				 Return (Local0)
			 }
		 }

Latest Mountain Lion is different:
Method (_DSM, 4, NotSerialized)
			 {
				 Store (Package (0x04)
					 {
						 "layout-id",
						 Buffer (0x04)
						 {
							 0x01, 0x00, 0x00, 0x00
						 },
						 "PinConfigurations",
						 Buffer (Zero) {}
					 }, Local0)
				 DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
				 Return (Local0)
			 }

GFX
RADEON 6850 XFX (HD-685X-ZNF) works great with GraphicsEnabler. Almost 50 FPS in Cinebench 11.
Haven't tested other ports.

OTHER
Kexts for ethernet and esata:
http://dl.dropbox.co...tAndJMicron.zip

I don't use USB 3 and it does't work natively. You have to patch DSDT section and use modified kexts to make it work:

Feel free to ask.
Cheers!

ps.
this was also tested with latest OSX vesion 10.8.2 and worked fine!

audio edits only for ML: if you don't want to patch DSDT put this into your org.chameleon.Boot.plisl file:
<key>device-properties</key>
<string>7700000001000000010000006b0000000200000002010c00d041030a0000000001010600001b7fff040028000000500069006e0043006f006e00660069006700750072006100740069006f006e00730000000500000000180000006c00610079006f00750074002d006900640000000800000001000000</string>
and install optimized alc892 from toleda for ML.

Hello,
may I ask why you chose Macmini5,3? Have you tried MacBookPro8,3? I'm running similar configuration - same CPU and Mobo but with Radeon HD7850. Right now I'm running MacBookPro8,3 and Clover instead of Chameleon.
I'm asking just because I'm curious. My actual config works quite fine.

I used macmini smbios because of cpu power management.
